Then to your situation, are you still holding the boarding passes? If you do, does your DL FF# show up there (DL xxxxxxxx)? As a DL PM you should also see 'sky priority' and 'elite plus'.
My hunch is that MU used your DL FF# as their FF#, thus it cannot be credited to Delta.
You are absolutely correct. Sadly, DL by phone and e-mail would not credit it to my DL # saying that MU credited the flights, so my guess is someone got my credit. Too confusing sometimes. It was a tough lesson to swallow, however, the only way forward is to avoid consolidator sites., although the price for business was good.
